STEAM-BOILER-COMPOUND FEEDER.

Application filed April 12,

To all whom it may concern:

Be it known that we, EDsoN H. TUTTLE, JOHN C. MILLER, and TRACY C.BALDWIN, citizens of the United States, residing at Conneaut, in thecounty of Ashtabula and State of Ohio, respectively, have invented newand useful Improvements in Steam- Boiler-Compound Feeders, of which thefollowing is a specification.

The object of our present invention is the provision of improved meansfor feeding to boilers a compound or other liquid agent calculated toremove and prevent the formation of scale in boilers.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawing, forming part of this specification Thefigure is a diagrammatic view illustrative of our improvement.

Among other elements our novel means comprises a pressure regulatingvalve 1. This valve per 86 is not of our invention, and hence it followsthat a pressure regulating valve of any appropriate type may be employedwithout involving departure from the scope of our invention as claimed.Vhen pressure is employed to feed the compound or agent to the steamboiler, the said regulating valve 1 is connected through a pipe 2 withthe boiler.

In addition to the regulating valve 1 our novel means includes a supplytank 3 on which is a sight gage 4, and a charging funnel 5; the saidfunnel 5 being connected by a pipe 6 with the tank 3, and the said pipe6 being connected at 7 wit-h the regulating valve 1 and being equippedwith a pressure gage 8 and a cut out valve 9.

The tank 3 is provided with a bleed line 10, and is connected throughthe medium of a pipe 11, preferably of copper with a sight feedregulator 12. The said sight feed regulator 12 is connected, in turn,and through Specification of Letters Patent.

the medium of a valved pipe 13, also preferably of copper with a conduit14 from the feed water heater to the boiler. By preference the saidconduit 14 is equipped with a thermometer 15.

It will be apparent from the foregoing that through the medium of ournovel apparatus a steam boiler may be expeditiously and easily suppliedwit-h a liquid compound or any other liquid agent for removing scale andfor preventing the collection of new scale.

lVe have entered into a detailed description of the construction andrelative arrangement of parts embraced in the present and preferredembodiment of our invention in order to impart a full, clear andeiiactunderstanding of the said embodiment. We do not desire, however,to be understood as confining ourselves to the said specificconstruction and relative arrangement of parts inasmuch as in the futurepractice of the invention various changes and modifications may be madesuch as fall within the scope of our invention as defined in ourappended claim.

Having described our invention, what we claim and desire to secure byLetters-Patent, 1s

Means for feeding a liquid agent to the feed water line of a steamboiler, comprising a supply tank, means for charging said tank, a sightfeed regulator, a pipe intermediate of the supply tank and saidregulator, and a pipe leading from the sight feed regulator and adaptedto be connected with a conduit in the feed water line; the said chargingmeans and the supply tank being also connected with a pressureregulating valve, and said valve being adapted, in turn, to be connectedwith a pressure line.

In testimony whereof we affix our signatures.
